In the development of the distribution automation system

the integrity and correctness of the network model are the premise and foundation to the application modules in the distribution automation system. Currently in the development of the distribution automation system

the basic network model is mainly led in from the geographic information system(GIS)or production management system(PMS). Because of lack of global verification in the process of introduction

it is difficult to check network model global integrity and correctness. A verification method is designed by making use of statistical and topological services in the distribution automation system to check the network model changes and quality globally. The feasibility and effectiveness of the method are verified by concrete project applications.
